Third, to pro-- Serial No. 605,544.

In the drawings, similar reference numerals refer to similar parts throughout the several views.

Referring to the drawing, the frame of our improved motor car consists of the top sills 1 and bottom sills 2. These sills are formed of tubing. As illustrated, the top sills are formed integrally of a U-shaped sill member, the rear or looped end 3 of the member forming a cross piece connection for the rear ends of the sills and being also adapted to serve as a handle for the car.

A U-shaped front cross piece member 1 is provided for the front ends of the top sills, the member 4 being telescoped into the ends Patented May 16, 1911. i 4

of the sills 1 and secured therein as by means of the pins 5.

The car illustrated is provided with main wheels 6 and 7 and auxiliary wheels 8. The main wheels 6 and 7 are arranged in the frame,that is, between the bottom sills thereof, while the auxiliary wheels are carried by the bars 9 and 10. The outer ends of these bars are connected by the rod 11. The bars 9 and 10 are braced by the braces 12 and 13, the brace 12 being arranged under the bar 9, while the brace 13 extends from the outer end of the bar 9 to the inner end of the bar 10.

The top and bottom sills are connected at their rear ends by the vertical cross pieces 14.. These cross pieces are preferably X- shaped and are provided with collars 15 at their ends adapted to receive the sills and with seats 16 for the sills. The top sills are secured in these seats by means of the T- clamping bolts 17.

The bearings 18 for the axle 19 of the rear wheel 7 are provided with seats 20 for the bottom sills, and are secured by means of the bolts 21 arranged through the bottom sill seats of the vertical cross pieces 14:, and the sill seats on the bearings. The axle 22 for the front wheel 6 is arranged on bearings 23 provided therefor on the casings 24. These casings are provided with clamps 25 for the bottom sills 2 and clamps 26 for the top sills 1, the clamps being formed integrally therewith, as is also the bearing 23 for the axle and the bearing 27 for the crank shaft 28 of the engine. The clamps 25 are arranged between the bearings 23 and the cank casing portions of the casings, while the clamps 26 are arranged upon the upper ends of the casings.

The clamps 25 and 26 are in the form of holes adapted to receive the sills, having slits 29 on their inner sides, and ears 30 through which the clamping bolts 31 are arranged. The casings 24 are thus adapted to form frame members, as well as to incase the crank shafts and support the bearings for the crank shafts and axle. The driving connections for the crank shaft to the axle are also inclosed by this casing, and in the structure illustrated, consist of the pinions' 32 on the crank shafts and the gears 33 on the axle with which the pinions are arranged to mesh.

The side members 35 of the casing are provided with bearings 36 for the outer ends of the crank shafts. The casings 24 are provided with seats 37 for the wheel bar 9. These seats are arranged upon the sill clamp 26. The wheel bars are secured in these seats by the clamps 38. The securing bolts .39 are provided with thumb nuts 10 so that the clamps can be readily released to permit the removal of the auxiliary wheel bar when the structure is knocked down for shipment or storage.

The brace bar 12 is provided with a hook 41 at its inner end adapted to engage the ear 12 on the side member 35 of the inner casing. The auxiliary wheel bar 10 is secured to the bottom sills by means of clamps so that it can be readily removed. The clamp for the outer sill consists of the top member 4-3, which engages the top of the sill 2, the intermediate member 4:4: which is interposed between the bar 12 and the sill, and the bottom member 45 which is embraced by the U-bolt 46, the bolt being arranged through the top member 43. See Fig. I.

The bar 10 is secured to the inner sill 2 by means of a double clamp QUE-that is, it has a clamp member adapted to embrace the sill and one adapted to embrace the bar. This clamp is provided with an ear 48 adapted to receive the hook 49 on the brace bar 13, see Fig. II. lVith the wheel bars 9 and 10 thus secured, they serve as frame bracing members or cross pieces. e also provide the frame with a truss, which, in the structure illustrated, consists of the truss cross pieces 50, having collars 51 at their ends adapted to receive the sill members. These cross members are bent toward each other and connected by the strap 52, see Fig. IV. The frame pieces are preferably formed of tubing, as illustrated, on account of strength and lightness. The engine cylinders53 are upon the casings 24, the engines preferably used being of the twocycle type.

The fuel reservoir 54 is mounted upon the top sills to the rear of the front bar 9. The reservoir is cylindrical in form and is arranged in a horizontal position, it being supported by the straps 55, which are looped around the sills at 55. The reservoir is secured upon the supports 55 by means of the straps 56, which are arranged over the reservoir and secured by means of the bolt 57, which also secures the straps 55.

A platform-like seat 58 is arranged at the 'rear of the reservoir and is supported upon the top sills by means of the spools 59 through which the clamping bolts 60 are arranged. A partof these clamping bolts are eye bolts, as 60, shown in Fig. V. Others, as 61, are common bolts provided with clamp members 62 for the under sides of the sills. Under the seat and in front of the truss member described, we support a box 63 by means of the rods (54. This box is provided with a lid (35, forming a part of the platform 58. The spart coil 66 is supported under the box (53. The foot board 69 is mounted upon the front bar brace 12 and the rear auxiliary wheel bar 10, as shown in Fig. 11.

The timer preferably consists of a sleevelike adjustable member 70 mounted upon the bearing for the crank shaft and the inner side member 35 of the casings 2%, see F ig. III. This member 70 is retained upon the bearing by means of the pin 71 which is arranged through a slot 72 in the member, a spring '73 being arranged on the pin, as illustrated. A pair of contact members 75 are mounted on this member 70 and suitably connected by the wires 76. A coacting contact member 77 is mounted on the end of the crank shaft, the contact member being a roller mounted on a pin 78, which is arranged atone side of the center of the crank shaft, as shown. The member 70 is connected by the link 7 9 to the lever 80. e thus provide a simple and effective timer without the addition of a special timer shaft and driving connections therefor. We preferably provide grease cups 81 for the axle bearings 23, the bearings being provided with suit-able bushings 82.

The lever 80 is arranged at the forward end of the seat 58, as is also the throttle lever 83 and the switch 84, see Fig. II. The carbureter 85 is arranged between and slightly to the rear of the engine cylinder, see Fig. IT, and connected to the reservoir by means of the pipe 86 and to the cylinders by means of the binding pipe 87. The brake shoe 88 is carried by the rock shaft 89, which is mounted on the sleeve-like support 90 on the top sill, see Figs. I and II.

With the parts thus formed and arranged, they may be readily and easily formed and assembled. The frame pieces are secured together by clamps, so that the connections are very rigid and secure and are not likely to loosen in use. This is a very desirable feature, as in use, the cars are ordinarily exposed to all kinds of weather and severe and careless use, and in operating them, are

comparatively light weight and it is desirable that the engine shall be mounted directly upon the frame.

By connecting the engine directly to the casing and the casing to the traction wheel axle, the frame is largely relieved from the strain of the weight of the engine, and of its operation.

We have illustrated and described our improvements in detail in the form preferred by us and in the form in which we have embodied the same in practice. We are aware, however, that considerable variations in structural details are possible, but as such variations will no doubt suggest themselves to those skilled in the art to which this invention relates, we have not attempted to illustrate or describe the same herein, but we desire to be understood as claiming our invention specifically in the form illustrated, as well as broadly within the scope of the appended claims.
